Technology and Automation: Demonstrate your familiarity with technology tools and systems that support operations, such as ERP software, data analytics, and process automation.

Risk Management: Discuss your approach to identifying potential operational risks, developing risk mitigation strategies, and ensuring business continuity.

Regulatory Compliance: If applicable to your industry, be prepared to discuss how you've managed compliance with industry regulations and standards.

Performance Metrics and KPIs: Explain how you've used key performance indicators (KPIs) to measure operational success and track progress toward goals.

Change Management: Be ready to talk about how you've managed organizational changes, transitions, and process implementations effectively.

Customer Focus: Discuss how you've aligned operations with customer needs and expectations to ensure a positive customer experience.

Interdepartmental Collaboration:Emphasize your ability to collaborate with different departments to achieve cross-functional goals and drive organizational success.

What is the purpose of operations management?

Operations management is the field that focuses on designing, overseeing, and optimizing business processes to ensure efficient production and delivery of goods and services. Its purpose is to enhance productivity, minimize costs, and improve customer satisfaction.

Explain the concept of process optimization.

Process optimization involves analyzing and refining existing business processes to make them more efficient. It aims to eliminate bottlenecks, reduce waste, improve cycle times, and enhance overall productivity.

Formula: Process Efficiency = (Output / Input) * 100

Example: If a manufacturing process produces 800 units with 1000 inputs, the efficiency would be (800 / 1000) * 100 = 80%.

What is the difference between push and pull production systems?

In a push system, production is driven by forecasts and products are pushed into the market based on anticipated demand. In a pull system, production is triggered by actual customer demand, reducing inventory levels and the risk of overproduction.

Explain the principles of Total Quality Management (TQM).

Total Quality Management aims to achieve continuous improvement in products, processes, and services. It involves fostering a culture of quality, empowering employees to contribute to improvement efforts, and using quality tools such as PDCA (Plan-Do-Check-Act).

Define the concept of lead time in operations.

Lead time is the amount of time it takes for a product to move through the production process, from order placement to delivery to the customer. It includes processing time, queue time, waiting time, and transportation time.

What is the EOQ (Economic Order Quantity) model?

The EOQ model is used to determine the optimal order quantity that minimizes the total inventory costs, including holding costs and ordering costs.

Formula: EOQ = √((2 * D * S) / H)

Where D = Annual demand, S = Ordering cost per order, H = Holding cost per unit per year.

Explain the concept of JIT (Just-In-Time) production.

JIT production aims to minimize inventory levels by producing and delivering products only when they are needed. It reduces waste, improves efficiency, and relies on tight coordination between suppliers and manufacturers.

What is the role of Six Sigma in operations management?

Six Sigma is a data-driven methodology that focuses on minimizing defects and variations in processes. It aims for process improvement by reducing defects to a level of 3.4 defects per million opportunities (DPMO), achieving high quality and customer satisfaction.

Define the concept of bottleneck in operations.

A bottleneck is a point in a process where the capacity is limited, causing delays in the entire process flow. It restricts the flow of work and can result in longer lead times and reduced overall efficiency.

Explain the concept of kaizen.

Kaizen is a Japanese term that means 'continuous improvement.' It involves making small, incremental improvements to processes, products, or services over time. Kaizen encourages employees at all levels to identify and suggest improvements, leading to a culture of ongoing enhancement.
